Rust program to check specific bit is HIGH (1) or LOW (0)

Here, we are going to learn how to check specific bit is HIGH (1) or LOW (0) in Rust programming language?
Last Updated : September 24, 2021

Problem Statement

Here, we will create an 8-bit integer number and then we will check 3^rd bit of the number is HIGH (1) or LOW (0).

Program/Source Code

The source code to check specific bit is HIGH (1) or LOW (0) is given below. The given program is compiled and executed successfully.

// Rust program to check specific 
// bit is HIGH or LOW

fn main()
{
    let num:i8 = 8;
    let mut res:i8 = 0;
    
    res = num & (1<<3);
    if res>0
    {
        println!("3rd bit is HIGH");
    }
    else
    {
        println!("3rd bit is LOW");
    }
}

Output

3rd bit is HIGH

Explanation

Here, we created an 8-bit integer variable num with an initial value of 8. Then we checked 3^rd bit of the number is HIGH (1) or LOW (0) and printed the appropriate message.
